About Selecting Temperature Sensors

Quick-Connect Thermocouple Probes for Surfaces

The probe tips come attached to mounting connections for fast installation.

Thermocouple Probes for Surfaces

Touch the exposed probe tip to your surface for a quick reading.

Hand-Held Thermocouple Probes for Surfaces

Often used with thermocouple thermometers, these probes have a handle for a comfortable grip.

Threaded Thermocouple Probes for Surfaces

Keep an eye on the surface temperature of your equipment—these probes thread directly into a tapped hole for continuous monitoring.

Wireless Thermocouple
Transmitters for Liquids and Gases

Monitor your system’s temperatures directly from your smart device. These battery-powered transmitters send real-time data to smartphones and tablets via Bluetooth, so you can easily confirm your processes are functioning properly. Good for route-based monitoring and preventative maintenance.

Data-Logging Hand-Held Thermometers

Measure and store temperature readings and upload the data to a PC.

Fluke High-Accuracy Data-Logging Thermometers

Store up to 500 readings on these thermometers and determine temperature within ±0.75° F accuracy.

Extended-Life Data-Logging Thermometers

For more accurate and consistent readings than thermometers with thermocouple probes and a longer service life, this thermometer has a resistance temperature detector (RTD) probe.

High-Temperature Hand-Held
Thermometers with Calibration Certificate

These thermometers have a thermocouple probe that can handle extreme temperatures, and come with a calibration certificate traceable to NIST that states they have passed a test for accuracy.

High-Temperature Water-Resistant
Hand-Held Thermometers

The thermocouple probe measures temperatures up to 500° F, and the thermometer housing meets IPX7 for protection from temporary submersion.

Fluke High-Accuracy Hand-Held Thermometers

Designed for laboratory applications, these thermometers determine temperature within ±0.75° F accuracy.

Infrared Thermometer Transmitters

Noncontact Infrared Thermocouple
Probes for Surfaces

Monitor the temperature of hazardous, sensitive, and hard-to-reach surfaces without touching them.

Noncontact Temperature Sensors for Tanks

Take your tank’s internal temperature with these sensors that sit on the outside walls.

Clamp-On Noncontact
Temperature Sensors for Pipe

Check the inside temperature of your pipe from the outside.
